RESILIENT PNEUMATIC WHEEL.

Apbncati'on filed January 25, 1915. serial No. 4,323.

V.To all whom it may concern:

Be it known that I, Davie D. S'roNEn, a

citizen of the United States, residing at Cin-V cinnati, in thecounty of Hamilton and State vof Ohio, have invented a new and useful Resilient Pneumatic Wheel, of which the following isa specification.

The device forming the subject matter of this application 'is a vresilient wheel and one object of the present invention is to provide adevice of the type above mentioned in which the yieldable or inflatable element is housed completely within the contour of the ceeds, the invention resides in the combina tion and arrangement vof parts and in the details construction hereinafter described and claimed, it 'being understood that changes in the precise embodiment ofthe invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawing: Figure 1 shows the invention in side elevation, parts being broken-away; Fig. 2 is a transverse Section; Fig. 3 is a perspective showing one of the blocks which make up the yieldable" band; Fig. 4 is a perspective showing a slightlyr modified form of securing block.

In the accompanying drawings the invention is shown as comprising an annular', plate-like body 1 equipped with any suitable means 2 for holding a tire 3 of any desired-form. In its inner edge, the. annular body 1 is provided with a plurality of notches l defining projections Applied to opposed faces of the annular body 1 are side plates 6 comprising ribs 7 which bear slidably upon the opposite faces of the body 1. If desired, packing strips 8 may be seated in the inner faces of the ribs 7 to effect a tight joint between the side portionof the wheel, a' puncture or. injury to the inflatableelement thus being at its periphery' plates and the body 1.;A Injthefinneredges of the side plates 6, grooves or seats9,ar

ranged m circumferential The side plates 6 are provided, with' coperating hub-forming parts 10 united by securing elements 11. elements V11 may be tubular and may constitute'a part of a valve l2. i

The valve 12 opens into a pneumatic elementA preferably in the-form of a tube 111,

the latter surrounding the hub 10-1O of the i located between 'the side.'

wheel and being plates 6. Surroundingr the tube 14 is a yieldable band which is a composite structure, the band comprising a iiexible strip 16 and blocks 17 which areattached to the strip. In the outer edges of the blocks 17 circur. ferentially extended grooves 18 are formed., the grooves of each block 17 being separated by a rib 19. Secured to the outer edge of each bleek 17 and extended across the rib 19 is a projection or rod 20. The rib 19 and the projection or rod 20 may be described as a transverse Aabutment on the block 17. It desired, the side plates 6 may be connected, between curing elements 21 silient inflatable tube 14 maybe surrounded by a covering 15 which maybe resilient and in anycevent is yieldable.`

When the tube 14 is inflated through the medium of the valve panded radially of the the flexible strip 116, the blocks 17 thereon being carried outwardly until the cross pins or projections 2O on .the block 17 enter and engage in the tseats 9 which are fashioned in the side plates 6. The projections 5 on the annular body 1 enter the grooves 18 in the blocks 17 and, under circumferential further circumferential movement 'between order, are located."

One of the securing' Ithe tube 111 is ex-v wheel and expands` 'pressnre, engage with the ribs 19 to prevent f 7 of the side plates 6 and the annular body 1. The rod 20 and the seats'9 constitute interengaging parts which prevent a relative rotary movement between the side plates 6 and the blocks 17.

Having thus described the invention, what is claimed is:-

1. A resilient wheel comprising an annular body having projections upon its inner edge; side plates between which the body slides and provided with cooperating parts defining a heb, the side plates being provided with circumferentialiy arranged seats; an inflatable element .surrounding the hub; a yleidable strip surrounding the inatable element; land blocks secured to the strip, the

Y blocks having grooves in their outer faces,

the grooves being adapted to receive the projections on the body, the blocks being provided with transverse abutment-s coacting with the projections to form stops for limiting the circumferential movement of the body, portions of the abntments being received in the seats of the side plates.

i2. A resilient wheel comprising an annular body having projections upon its inner edge; 'side plates between which the body slides; a resilient element located between the side plates; a yieldable strip surrounding the resilient element; and blocks secured the blocks having grooves 1n the grooves'being adapted to the strip, then' outer faces,

to receive the projections on the body, the

blocks being provided with transverse abut- Inents coacting with the projections toy form stops for limiting the circumferential movement of the body, portions of the abutments being received in the seats of the side plates.

3. A resilient wheel comprising an annular body having projections upon its inner edge; side plates between which the body slides and provided with circumferentially arranged seats; a resilient element between the side plates; a yieldable band surrounding the resilient element and provided with grooves in its outer face, the grooves being adapted to receive the projections, the band being provided with transverse abutments coacting with the projections to form stops for limiting the circumferential movement of the body, portions of the abutments being received in the seats of the 'side plates.

In testimony that I claim the foregoing as my ow ,have hereto alixed my signature in the gresence of two Witnesses.
